Bernard Controls

Bernard Controls, founded in 1949 and headquartered near Paris in Gournay-sur-Marne, is one of France's longest-established electric valve actuator manufacturers, still family-controlled and exporting to roughly eighty countries. The product portfolio centers on multi-turn actuators in the OSQ and OSE ranges and part-turn quarter-turn actuators in the OQ and OSE-Q families, complemented by intelligent control units with torque and position measurement, fieldbus communication, and non-intrusive setting via Bluetooth. Bernard Controls holds a particularly strong position in nuclear power: its actuators are qualified for nuclear safety-related service in both France and China, where the company established local manufacturing, and its equipment is installed across the EDF fleet and exported reactor projects. Beyond nuclear, the company serves water treatment, oil and gas, mining and HVAC markets with corrosion-protected variants and explosion-proof executions for ATEX zones. The brand differentiates on engineering responsiveness — custom actuator-gearbox packages and severe-duty configurations are routinely built from standard platforms — and on the longevity of its installed base, with units running for decades in nuclear and district heating service across Europe and Asia.
